Re: Question regarding Tuning Servo motors

Have you ground the shield to the power ground on only one end of the
encoder cable?
Have you ground only one end of the servo motor power cable on only
one end as it is supposed to be?
How long is your encoder cable?
I take it that you have a differential encoder with ten leads?
Are you using a line driver?
